摘要
分析了高寒草地资源的时空分布特征及其在环境条件影响下的阻滞增长动态 ,依据生态学中的 K / 2 值原理组建草地资源保护性利用的模型 .依据在甘南玛曲县草地的调查结果 ,分别对山地草原化草甸、山地真草甸和沼泽草甸等草地的资源 ,建立了相应的保护指标 。
The temporal spatial distribution of alpine meadow resources and its logistic growth dynamics influenced by the environment condition were analyzed to build up the protected utility model of meadow resources according to K/2 theory in ecology. On the basis of investigations at Maqu in Gannan, the protection indexes were established and the management strategies were presented for stocking farms to make an optimal utilization of meadow resources.
